Pot Croze

Ever since i read about the Pot Croze on Sean Hellmans blog, it's been in the back of my mind to build one for myself, today, whilst having a bit of a sort out of some old hardware in the shed, i found the perfect little blade for making one.

Ive designed my Croze to sit in my B&D Workmate, whereas if i remember correctly, Sean incorporated his into his bench.

The plywood disc i used to mount the blade on is screwed and glued to a piece of scrap pine that locates in the jaws of the Workmate, the bottom of the disc sits on the top of the bench and the blade sits about a 5/8 of an inch off the deck so to speak.

So why use a Croze?, well when making Shrink Pots, you need to cut a groove on the inside of the pot for the base to sit in and the upper edge of this groove needs to be square, until now I've free handed it and it has shown in the quality of some of the base cuts I've made, they work, but in some cases they are not particularly pretty,  but this little device makes cutting the upper edge of the groove so much easier, plus it's more precise and gives a good square edge to work with, meaning a neater and higher quality end product.

To use the Croze, you place the pot over it and then rotate the pot against the blade, the picture to the right shows it in operation, the blade I've used is just an old craft knife blade, the three forward most screws hold the blade in place, but i can also alter the depth of cut by loosening the rearward screw and sliding the blade forwards or backwards in the integral slot that is in the end of the blade.

Why two screws on the left hand edge of the blade?, simple, i turn the pot counter clockwise to cut the groove and there is a lot of pressure in that action, two screws ensure everything remains where it should be when I'm turning the pot against the blade, or the other way to look at it, it's over engineered.
